The current of the St. Lawrence, from Oswegatchee upwards, is much more gentle than in any other part between Montreal and Lake Ontario, except only where the river is considerably dilated, as at lakes St. Louis and St. François; however, notwithstanding its being so gentle, we did not advance more than twenty-five miles in the course of the day, owing to the numerous stops that we made, more from motives of pleasure than necessity. The evening was uncommonly fine, and towards sun-set a brisk gale springing up, the conductor judged it advisable to take advantage of it, and to continue the voyage all night, in order to make up for the time we had lost during the day. We accordingly proceeded, but towards midnight the wind died away; this circumstance, however, did not alter the determination of the conductor. The men were ordered to the oars, and notwithstanding that they had laboured hard during the preceding day, and had had no rest, yet they were kept closely at work until day-break, except for one hour, during which they were allowed to stop to cook their provisions. Where there is a gentle current, as in this part of the river, the Canadians will work at the oar for many hours without intermission; they seemed to think it no hardship to be kept employed in this instance the whole night; on the contrary, they plied as vigorously as if they had but just set out, singing merrily the whole time. The French Canadians have in general a good ear for music, and sing duets with tolerable accuracy. They have one very favourite duet amongst them, called the “rowing duet,” which as they sing they mark time to with each stroke of the oar; indeed, when rowing in smooth water, they mark the time of most of the airs they sing in the same manner.
